PERFORMANCE OF CURRENT QUALITY COMMERCIAL JET FUEL IN THE SUPERSONIC TRANSPORT AIRFRAME AND AIRCRAFT ENGINE FUEL SYSTEM TEST RIG FINAL REPORT FEDERAL AVIATION AGENCY CONTRACT NO. FA-SS-65-3

摘要

The SST Airframe and Aircraft Engine Fuel System Test Rig was developed, designed and constructed under Coordinating Research Council Contract No. CA-34-61 as a means toward obtaining data to determine the effect of the airframe and aircraft engine fuel system environ¬ment on fuel quality requirements in the commercial supersonic transport. A total of five test series was conducted using two ASTM Type A Jet Fuels and one JP-5 Referee Jet Fuel. These tests were conducted at CRC environmental conditions representative of a 3500 nautical mile flight mission under Mach 3 or Mach 2.5 speed. The test results indicated no evident problem areas under the Mach 2.5 environmental conditions. The problem areas encountered under the four Mach 3 test series included the presence of deposits in the wing and fuselage tanks and vent lines, partial plugging of the engine fuel system filter, heat exchanger, and nozzle, and loss of heat transfer efficiency in the engine heat exchanger.
